    value.
  * memcached_behavior() now has the ability to set "buffering" so that

  * Fixed bug where key could be out of range of characters

0.11 Mon Nov 26 01:05:52 PST 2007
  * Added option to memcache_behavior_set() so that poll() can be timed out.
  * Fixed memory leak in case of using memcached_fetch_result() where no
    value was returned.
  * Bug fixed in memcached_connect() which would cause servers that 
    did not need to be enabled to be enabled (performance issue).
  * Rewrote bounds checking code for get calls.
  * "make test" now starts its own memcached servers.
  * Added Hseih hash (MEMCACHED_HASH_HSIEH), which is showing about 7%

  * Added append binary test.
  * Added MEMCACHED_BEHAVIOR_CACHE_LOOKUPS behavior so that you can save on
